To hold an error theory about morality is to endorse a kind of radical moral skepticism—a skepticism analogous to atheism in the religious domain. The atheist thinks that religious utterances, such as “God loves you,” really are truth-evaluable assertions (as opposed to being veiled commands or expressions of hope, etc.), but that the world just doesn’t contain the items (e.g., God) necessary to render such assertions true. Similarly, the moral error theorist maintains that moral judgments are truth-evaluable assertions (thus contrasting with the noncognitivist), but that the world doesn’t contain the properties (e.g., moral goodness, evil, moral obligation) needed to render moral judgments true. In other words, moral discourse aims at the truth but systematically fails to secure it. If there is no such property as moral wrongness, for example, then no judgment of the form “X is morally wrong” will be true (where “X” denotes an actual action or state of affairs). Advocates of this position include Hinckfuss 1987; Joyce 2001; Mackie 1977 (see MACKIE, J. L.). Various forms of moral skepticism—some of which are arguably instances of the error theoretic stance—have been familiar to philosophers since ancient times. (See SKEPTICISM, MORAL.) Error theoretic views can be controversial—as in the case of religion and morality—or widely agreed upon—as in the case of ghosts and phlogiston. It is important to note that error theorists maintain that the judgments in question are erroneous not merely because of the absence of any objective moral facts sufficient to render them true, but also because of the absence of any non-objective moral facts sufficient to render them true. There is, for example, a kind of moral realist who maintains that moral properties are objective features of the universe (see REALISM, MORAL). There is also a family of metaethical views according to which moral properties are in some manner constituted by us—by our beliefs, attitudes, practices, etc..
